坐椅,是電視機殼粉碎后制成。我國每年的施工建設產生的建筑垃圾達4000萬噸,產生的廢混凝土就有1360萬噸,清運處理工作量大,環(huán)境污染嚴重。另外,對既有建筑的再利用也是可持續(xù)發(fā)展的重要手段之一。在第一時間發(fā)現(xiàn)建筑可能出現(xiàn)的問題,及時進行修復與加固,既避免了可能出現(xiàn)的建筑事故,也基本解決了建筑過快老化損壞,不得不拆去重修的尷尬局面,及由此造成的大量經濟、資源、時間上的浪費,實現(xiàn)建筑使用的可持續(xù)發(fā)展。自動、實時地測量結構的環(huán)境、荷載、響應等,對結構的健康狀況進行評估,科學有效地提供結構養(yǎng)護管理的決策依據(jù),確保結構安全運營,延長結構使用壽命。2.1發(fā)展高新技術,應用結構健康監(jiān)測,實現(xiàn)可持續(xù)發(fā)展土木工程在實際使用過程中,會出現(xiàn)不同程度的損傷或性能退化,這將影響起承載能力和耐久性,甚至引發(fā)嚴重的工程事故,帶來重大的人員傷亡和經濟損失,產生嚴重的社會影響。走可持續(xù)發(fā)展迫在眉睫。“中國是世界上人口最多的國家,一項大資源被13億一除即變得微不足道,而一個小問題乘以13億就成了大問題。而且這樣一個優(yōu)良的發(fā)展環(huán)境已經受到并將繼續(xù)受到西方國家的急切關注。另外,高層建筑大量興起,地下工程高速發(fā)展,城市高架公路、立交橋大量出現(xiàn),并逐步實現(xiàn) 交通 運輸高速化、水利工程大型化?,F(xiàn)代土木工程造就的舉世矚目的建筑有:我國臺北的國際 金融 中心,上海金茂大廈,馬來西亞吉隆坡的石油大廈雙塔樓,法國的諾曼底斜拉橋等。建筑材料方面,高強度混凝土、高強低合金鋼、高分子材料、鋼化玻璃越來越多地出現(xiàn)在建筑上。建造技術方面,一些性能優(yōu)異的大型機械伴隨著各種極為有效的施工方法的出現(xiàn),使得人們開始能建造結構復雜或所處環(huán)境惡劣的土木工程。譬如我國的長城,埃及的金字塔等。My knowledge about civil engineering has been broadened since I became a student of Tongji engineering is a form of human bEings pursued it to change the natural environment for thEIr own , transportations, facilities, infrastructures are all included in civil development of civil engineering has a long seniors had left a lot of great constructions to example, Zhao Zhou Bridge is the representative of our Chinese civil engineering has a history of more than 1300 years and is still service at engineering has been so rapid development of the lot of new bridges have been constructed, and many greater plans are under is a large she is still well this era will be both exciting and rewarding for the Chinese Civil of course, civil engineering’s future is , civil engineers will be facing more plex should pay attention to the growing population and a lot of deteriorating should prepare for the possibility of natural meet grow needs in the future。通過一個學期土木工程概論課的學習,我已經深深地感受到土木工程涵蓋的廣泛,體味了前人取得的成就,也領悟了作為一名土木工程師的重大責任。以下是“土木工程走可持續(xù)發(fā)展之路論文”,希望能夠幫助的到您!土木工程也是建造各類工程設施的科學技術的統(tǒng)稱,它既指工程建設的對象,即建在地上、地下、水中的各種工程設施,也指所應用的材料、設備和所進行的勘測設計、施工、保養(yǎng)、維修等技術。作為一個重要的基礎學科,土木工程有其重要的屬性:綜合性,社會性,實踐性,技術 經濟 與 藝術 統(tǒng)一性。當然,我們不能沉浸于現(xiàn)已取得的輝煌成就,止步不前。we should also try to all the transportation deal with these problems, we will have to develop innovative and enterprising we should choose a way that we can go Mitigation may be a great only can it save money in the long run, but also avoid getting into an embarrassing situation in which we have to rebuild all the broken we should also use more environmentally friendly materials when designing or constructing new , to be a brilliant civil engineer is not , engineering is a synthetic not only depends on traditional mechanics, but also closely related to advanced Physics, Chemistry, Material Science, Computer Science and perhaps more are all in our civil engineering be a good civil engineer, we should have the ability to apply the knowledge, to design a system, a ponent, or a procedure of should also be able to conduct experiments and explain the , an engineer never works alone, so we shall cooperate with working team, and try our best to municate ’m very glad to be a student in this wonderful I will try my best to be a successful civil engineer, to make contributions to our .對土木工程的歷史、現(xiàn)狀和未來發(fā)展的認識1.1.1古代土木工程古代土木工程具有很長的時間跨度,它大致從公元前5000年的新石器時代到17世紀中葉,前后約7000年。公元6世紀建成的趙州橋,是世界上最早的敞肩式拱橋,于1991年被美國土木工程學會選為世界上地12個土木工程里程碑。期間建成的埃菲爾鐵塔、帝國大廈和金門懸索橋,至今仍不失為偉大的土木工程。結構理論方面,利用 電子 計算 機強大的運算和繪圖能力。1.2對土木工程的現(xiàn)狀的認識現(xiàn)今的土木工程,正日益同它的使用功能或生產工藝緊密結合。值得一提的是我國實行改革開放以后,綜合國力有了很大提高,已具備更大規(guī)模開發(fā)和利用水資源的條件,如三峽水利樞紐,南水北調工程等都是世界一流的大型水利工程。作為跨世紀的一代,這一大好形勢為我們提供了空前難得的施展才干、向國際水平沖擊的良好機遇?!眲⑽骼淌诖苏Z切實道出了我國的困難之所在。而土木工程,也必當立足長遠,走出一條可持續(xù)發(fā)展之路。因此,從建筑建成的一刻起,就要做好健康監(jiān)測、修復和加固的準備。
